DAVID A. BIEBINGER, OF MOLINE, ILLINOIS, ASSIGNOR T LA CEOSSE PLGVI C0,, 035 LA CROSSE, WISCONSIN, A CORPORATION OF WISCONSIN.

- To all whom it may concern:

Be it known that 1, DAVID A. BIEBINGER, (formerly of La Crosse, VVisconsim) a resident of Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Plows, of which the following is a full clear, and exact description.

The invention relates to plows and more particularly to the adjustable connections or couplings between the plow beam and the frame.

The invention designs to provide an improved adjustable coupling or connection between the beam and the frame, whereby the several adjustments desired to cause the plowshares or bottoms to travel at the desired angle or level in the ground may be made.

The improvements herein shown may be applied to a plow of the type shown in my application for Letters Patent, filed August 2%, 1912, Serial No. 716,925, of which the present application is a division.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Figure 1 is a plan of a portion of a plow embodying the invention. Fig. 2 is a perspective of the adjustable plow beam and coupling. Fig. 3 is a plan of the coupling, parts being shown in section. Fig. 4: is a side elevation of the improved coupling. Fig. 5 is a section taken on line 55 of Fig. 3.

The invention is illustrated as applied to the frame of a tractor-plow comprising a cross-bar 27, a side-bar 26, and a diagonal bar 29. A carrying-wheel 23 serves to support that portion of the frame, which is shown, it being understood that additional carrying-wheels are provided where necessary. This frame is usually adapted to op;

erate 'a series of plow-beams, only one or which is illustrated. I I

The beam is pivotally connected at its front end by a pin 52 to permit the plowbottoms, carried by said beam, to be raisedoutof and lowered into, the ground. The beam is made up of wrought metal bars to provide a strong and durable construction and each comprises a U-shaped bar 53 to each side of which a side bar 54: is secured.

Specification of Letters latent.

Patented Mar. is, rare.

' Divided and this application filed November I each pair of bars 5% and 55, there is a pair of brackets 57 between which a plow-standard 58, which carries a plowshare 59, is secured. A d-shaped bracket 66, through which the pin 52 extends, is secured to the front end of each beam-member 53 and is braced at one corner by a strap 53 connected to it and to the member Pins 52 at the ends of pin 52, hold the latter against lateral displacement. The connection between pivot 52 and the main frame comprises a bar bent to form a pair of side-arms or members 67 and a connecting portion 68 which is shaped to fit into the channel in bar 27 and is secured thereto by rivets 69. A U-shaped bar 70 between arms 67 is secured thereto by rivets 71.

Connections are provided whereby the front end of each plow-carrying frame may be adjusted to level the plow-bottom transversely and whereby the pivot may be adjusted verticallyto adjust the depth of the point of the plow, to vary the angle of the bottom and also to adjust the plow-bottom laterally to vary the angle of the landside relatively to the line of draft.

For the purpose of adjusting the depth of the plow point by raising and lowering pivot pin 52, an arch 76 is rigidly secured to the rear ends of arms 67 by bolts 77 and spaced the plow is in operation, will raise or lower the adjusting-screw 79. Screw 79 is rigidly secured to one of the lugs 78 by a U-shaped bar 83 and to the other lug 7S bva similar bar 8%. The latter lug 78 is formed with a slot 85 which is vertically elongated and through which one end of pivot-pin 52 passes.

Said lug is connected to one end of pin 52 by an eye-bolt 86 which extends through a laterally projecting ear 87 on ends of pin 52, without destroying the lat.-

eral angle of the plow-bottom.

By adjustment of screw 86 and by adjustment of nuts 88 thereon, one end of pivot pin 52 may be raised or lowered'to tilt it laterally to level it laterally, as desired. At the opposite end of the pivot 52, a device is pro vided for adjusting the plow-beam to vary the angle'of the landside relativelyto the line of draft. This device consists of an eye-bolt 90, through the eye of which one end of pin 52 passes. A slot 66 is formed in one side of bar 66 to permit fore and aft adjustment of one end of pin 52. Bolt 90 is slotted, as at 91, and a bolt 92 passesthrough said slot, to permit one end of pin 52 to be adjusted fore and aft, by nuts 91 on the screw of bolt 90, which engage a lug 93, which is secured to the side of the front end of the plow-beam. These connections thus exemplify means for adjusting the point of the plow-body vertically, the landside of the plow-body relatively to the line of draft, and forleveling the plow-bottom.

The invention is not to be understood as restricted to the details set forth, since these may be modified withinthe scope of the appended claims, without departing from the spirit and scope of the invention.

Having thus described the invention, what 7 lowering the pinbodily.
